Strength of Shear Connectors in Composite Steel and Concrete Beams |
Abstract |
The longitudinal shear flow in composite steel and concrete beams is transferred across the steel-flange/concrete-slab interface at a distance number of points by the dowel action of individual shear connectors, The strength of these dowels is affected by the presence of longitudinal cracks in the concrete slab which may have been formed by transverse bending moment on the slab or by splitting or shear forces that are induced by the dispersal of the dowel forces into the concrete slab. twenty-six push-out specimens have been tested to determine the effect of transverse reinforcement on the dowel strength of shear connectors that were imbedded in longitudinally cracked concrete slabs. It has been found that this post cracking dowel strength is affected by the stiffness of the transverse reinforcement but not by its strength. |
